Abstract

The invention provides an environment-friendly quick-drying water-based ink. According to the invention, composite resin formed by an acrylate emulsion or a vinyl acetate-ethylene copolymer emulsion and alkali-soluble resin is used as a connecting material; a cosolvent is composed of dimethylaminoethanol or 2-amino-2-methyl-1-propanol and one selected from a group consisting of ethanol, ethylene glycol, propylene glycol, isopropanol and methyl acetate; a triethanolamine buffering agent or a dimethylacetamide buffering agent is added into an ink system as a pH value stabilizing agent; and a wetting agent, a drier and pigments are added, so the environment-friendly quick-drying water-based ink is obtained. Since the composite resin is used as the connecting material, the tinting strength and ink color stability of the water-based ink are improved, and the obtained water-based ink system is small in viscosity and short in drying time; and due to addition of the pH stabilizing agent, changes in pH value and system viscosity during usage of the ink are reduced, and more stable printing effect is obtained.

Description

technical field [0001] The invention relates to the field of quick-drying ink, in particular to an environment-friendly quick-drying water-based ink. Background technique [0002] Solvent-based inks use aromatic compounds as solvents, which not only cause environmental pollution, but also are carcinogens, seriously endangering human health and living environment. At present, developed countries and regions are working hard to develop and use water-based inks to gradually replace solvent-based inks. Nowadays, water-based inks have occupied most of the market share in foreign countries. Many developed countries have introduced policies to restrict the application of solvent-based inks in the field of food and medical packaging. Pollution-free printing inks must be used. Contents of the invention [0003] In view of the prior art, the present invention provides an environmentally friendly and quick-drying water-based ink, which uses a composite resin formed of an acrylate e...
